` E. A. CLAUDER SHAMPOO APPARATUS Filed oct'. 25, 1957 Patented Nov. 28,1939 amr-Eo STATES SHAMPOO APPARATUS .Earle.A..Clauder, Madison, Wis.,assigner to Ever- Flo Manufacturing Company, Inc., a ,corporation ofWisconsin `Application,October. 25, 1937, ScrialNo. 170,925 l 3 claims.(ci. 299-144) This invention relates to improvements in 4shampooapparatus, Yand moreespeeially inappa- Aratus designed '-to supply bothwater and liquid .soap vto the head.

The :present application is a continuation-in- :part of my application,`Serial No. 146,687, -ed June 5, 1937.

One feature of this invention is lthe Aprovision of a deviceaadapted tobe held with one hand and designedforquick dispensing' of either wateror soap, orbOth, the control oi' such dispensing being by the thumb ofsaid hand withoutthe'necessity-oi shifting the hand; another feature ofthis invention is the Iprovision of means vfor heat eX- change betweenwarmwater and the liquid soap so that saidlsoapmay beapplied -to thehead in a warmed condition; yet another feature of this invention is theprovision'ofV an annular nozzle'for the -wate-r supply, with -the soap`nozzle yso -arranged as to discharge soap within the area 'bounde'd'bysaid annular nozzle; a 'further feature of this invention is theprovision of an improvedcontrol valve; other features and advan-V tagesVof this invention will be apparent from the following speciiication andthe drawing, 4in which: l

. lg. (l is a side elevation,A partly broken away, cf lshampoo.apparatus embodying this invention; Fig. 2 isa vertical sectional AViewof the handle and associatednozzles land valves; Fig. 3 vis .atop planview of the handle of Fig. 2 and Fig. 4 is a bottom vkplan View of -the-nozzles and a portion of the handle.

In connection with the shampooing of. hair, and particularly -womenshair, it is desirable to have a convenient supply -of both warm waterand soapso arranged that they may be used individnally, intermittentlyorsimultaneously. It is also oi considerable advantage if the dispensingapparatus vfor the soap andwater can-be operated byone hand, leaving theother .free to` adjust a towel, work the soapor waterginto the hair, andotherwise care'for the-needs ofthe :person whose head is beingshampooed.

The application oi cold liquid soap (and soap atfroomftemperature,may bethus considered in comparison with the warm water used) to a head afterpreliminary rinsing with warm water is uncomfortable to the patron.Moreover, relatively cold soap does not lather as well as warmed liquidsoap. My shampoo apparatus, therefore, provides means whereby the soapsupply can be warmed substantially to the temperature of the water sothat its application to the scalp causes no unpleasantness, andtheconversion of the soap into va'lather is facilitated. y. It has yalsobeen found that the use of vanannular nozzle is .of `considerableadvantage, ysince it provides good distribution of va plurality of4small .jets ofvwater. flthas alsobeen found kan advantage toy-.supplythe liquid soap .to the hair within the area or space bounded by theannular nozzle, or the jets of water issuing therefrom, Yso that moresoap canlbe placed -on the hairpeven when Hthe water is flowing `fullforce from `an annular nozzle, without Sits being immediately washedaway and-lost. l

In'thefparticular.embodiment of my invention illustrated 'herewith `avsubstantially cylindrical handle VIt! is shown provided wtih an annularnozzle I-I adapted to discharge'water,and-aseo# ond nozzle l2 adapted todischarge-soap. Convenientime'ans for supplying both-soap and water tothe handle, land'thus to the nozzle, is here vshown as eomprisinga mainYhose I3 adaptedto be coupled'to a conventional faucet M by anyconvenient means, and a second smaller hose 'l5 adapted to @haveliquid-soap gravity fed there" through from ian elevated soap containeri6, which may, for example, be mounted'on a wall as by the bracket I1.

The handle Il] has formed therein two distinct chambers, :l-iland i9,here vshown as concentrically arranged. The chambers are not incommunication with each-other, but are in heat transfer relation so thatthe liquid flowing through the chamber iE, namely warm water, cantransfer heat tothe liquid in the chamber i8, such as soap.

The chamber I9 receives water fromlthe large hose i3 y,and passes-itinto the end chamber 42i?, which `is adapted to communicate with theannular nozzle!! through thefopening 2l controlled by the valve memberl22. The lchamber receivesl-iquid soap from the smaller hose l5, and isin communication-with the-nozzle l2 through the `opening orfpassage 23controlled-by the valve member 26. The size ofthe soap chamber ll-ii'isifo t suiiicient'that only'a portion of the soap'therein will-bevdischargedthrough the nozzle i2 at any givenftime;Y thusinsuringsuiiicient 'length V'of stay of "the soap inthe chamberl8'that'itapproaches the temperature of the warmwater flowing throughthe chamber or passage i9.

The valve controlling the communication of the chamber I8 with thenozzle l2, and thus the flow of liquid soap therethrough, is of thenormally closed type adapted to be held in open position only by manualpressure on the button 25. That is, the spring 26 urges the valve 24into closed position, and as soon as pressure is removed by release ofthe thumb from the operating button 25 the valve at once returns to thisclosed position.

The valve member 22, on the other hand, although provided with a spring21 urging it into closed position, is provided with mechanism whereby itmay be manually operated and locked in open position if desired. Thismechanism comprises a lever 28 cooperating with a stud or member 29. Thelever 28 is provided with a straight portion 30 connected to the stem 3lcarrying the valve member 22 a portion 32 inclined or angularly disposedwith respect to the direction of the motion of the valve member 22; anda portion 33 adapted to be contacted by the thumb of the user. The stem3l and valve member 22 are rotatable about an aXs coinciding with thestem 3|, and thus with the direction of movement of the valve member 22.Since the lever 28 is carried by the stem, it is similarly rotatable,and downward pressure upon the portion 33 of the lever (speaking withrespect to the apparatus as shown in Fig. l) efects movement of theangular portion 32 with respect to the member 29 in contact therewith,which movement results in displacement of the member 22 from its seat toopen the valve. The angularly disposed portion 32 is provided with adepression 34 adap-ted to receive the member 29 when the valve is fullyopen in order tolock it in that position, so that the thumb may beremoved. Thus, even when the water is owing from the annular nozzle,soap may be supplied to the head of the person being shampooed bymanipulation o-f the button 25. On the other hand, when it is desired tostop the ow of water, the lever may be ilicked upwardly with thethumb,'causing a change in relationship between the angular portion 32and the member 29 such that the valve member 22 may return to closedposition under the urging of the spring 21. It will be noted, as may beparticularly seen in Fig. 3, that the operating portion of the lever andthe button 25 are so arranged that they may be selectively operated bythe thumb of the hand holding the handle IB without any necessity forshifting the position of the hand, or using the other hand.

In operation, thek valves controlling the flow of water through thefaucet Ill would be adjusted to provide water of the desiredtemperature. The lever 28 would then be moved to a position permittingflow of water from the openings 36 in the annular nozzle 3B, and thehair would be given a preliminary rinse to warm and wet it. The flow ofwater may then be discontinued, if desired, and sucient soap dischargedVfrom the nozzle I2, by operation of the button 25, to enable a lather tobe worked up in the hair. A ow of rinsing water could then be again usedfrom the nozzle ll, under control of the lever 28. Moreover, water andsmall amounts of soap may be simultaneously applied to the hair, ifdesired, to insure a moist lather. It will be noted that the dischargeof both soap and water is fully under the control of the hand holdingthe shampoo apparatus, with no necessity for manipulaprior art.
